Fascinating stuff. Thanks for making this video. I feel an enormous amount of envy towards Professor Merrifield's ability to do backyard astronomy, given that I am tragically embedded within a distinctly *light-polluted* major American city (Philadelphia; West Philly, to be exact). A few months ago I was back home in New England, and I looked up at the sky and was amazed to see hundreds of stars. It was still a mildly light-polluted area, but it took my breath away. I hadn't seen a night sky lit up like that in a very long time. I love my city, but 15 years in Philly has utterly deprived me of the wonders of naked eye astronomy. It's a high price to pay for an astronomy nerd. At least I got you, Brady. :) Thanks again.

Actually we are within the leading edge of the Orion armlet a density wave recently named the "Radcliffe wave" which due to its undulating nature As for the supernovae breakthrough wave an astronomer in Argentina was able to see one a few years back. It is also worth considering that since stars form in a group you will get bursts of core collapse supernovae (astronomically speaking) as you might get several massive stars of similar ages having formed from the same cloud. Statistically they average out but you might get multiple waves of supernovae with the number of supernovae and time progression between them increasing up until the mass limit in recent times geologically speaking the Earth had a close encounter with a core collapse supernovae within around 150-200ish light years away which may have played a role in why we are here to observe the universe in the first place though its environmental effects on our planets climate.

He hint's at the "Monte Carlo fallacy" for where to look for new Super Novas.

That the supernova is a result of neutrino pressure is a new detail. I imagine those neutrino detectors are supernova detectors as well?

Is machine learning being used to make predictions of what start will go supernova?

Cool. I didn't know spiral arms were a wave phenomenon. Does that mean it's sort of dictated not directly by gravitational waves (as the public probably mostly knows about them now, [waves in the structure of spacetime]), but rather by the gravitational wells created by stars beginning to affect other stars, and then as motion starts to take place, waves caused by inertial aspects 'follow' the gravitational effects around? Kind of like you get waves in a backup on the highway, cars reacting down the line based on what they see directly in front of them, which probably has no direct relation to what is happening at that instant at the FRONT of the backup. Know what I mean? So maybe spiral arm waves are created by stars reacting to stars reacting to stars, regardless of what the original spirals started out 'looking' like? Kee-ryst that's a busy paragraph, but that's what I wrote. I hope the question came across the way I meant it to...

Now that we can see this from here, is that supernova over now that we see it since it took ages for the light to travel this far?

Silly question, perhaps, but should we be worried acout getting caught up by the density wave? Would being in a star-forming spiral arm make a noticable difference for us here on earth?

I'm intrigued by the phrase about neutrinos interacting with gas at 2:28. The only thing I know (or think I know) about neutrinos is how little they interact - to the point of being very hard to detect. So what's happening here to make them behave differently?

@davidross5525

4 жыл бұрын

To the best of my understanding, nothing different is happening, just the shear number of neutrinos and the density of gas means that a significant number of interactions happen. The amount of energy released as neutrinos during the supernova is about 10000 times more than is released as photons, and around 5% of the neutrinos released end up interacting with the expanding gas. So thats a big explosion.
